NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application led November 26, 1905. Serial No. 345.117.

T0 @ZZ whom' t may concern.-

Be it known that I, HARVEY NELSON ROTHWEILER, a citizen of the UnitedStates, residing at Seattle, in the county of King and State of1Washington, have invented a new and useful Improvement in Non-Refillable Bottles, of which the following is a specification.

My invention is in the nature of a non-re- 'lillable bottle designed forcontaining spirituous liquors, proprietary preparations, tablecondiments-such as catsup, sauces, &c.- and any other materials inliquid form in which the refilling of the bottles with a surreptitioussubstance is to be prevented.

My invention consists in the novel construction and arrangement of thebottle in combination with a valve, a sealing-cap, and dispensingdevices designed to be vfilled and also discharged under anair-pressure, as hereinafter fully described with reference to thedrawings, in which- Figure 1 is a vertical central section of my newbottle, and Fig. 2 is a sectional detail of the cap.

A represents a glass bottle having its neck portion slightly contractedat a2 and having an external rib or projection a a short distance belowthe mouth of the bottle.

B is a tube, of any desired material, but preferably of glass, andextending nearly the full length of the body of the bottle.A This tubeis swelled atb Anear its upper end to a larger diameter, which swelledportion forms a support for the'tube, which rests upon the contractedportion (1,2 of the bottle-neck and holds the lower end of the tubeconcentrically in the bottle and suspended about onequarter of an inchfrom the bottom. This tube is fixed firmly in the neck of the bottle bya filling of cement c, which surrounds the swelled portion of the tubeand nils the space between the same and the inside surface of thebottle-neck.

The upper end b of the tube B above the swelled portion is somewhatsmaller in diameter than the lower part and forms at the point where itenters the swelled portion a valve-seat against which rests frominternal pressure a valve D. This valve, as shown, is globular, but maybe of any shape, and pref'- erably has on its upper surface a softpacking of rubber'or other material. The valve is made with arigidly-attached stem d, which may be made in one and the same piecewith the valve or may be made separately and screwed in. The valve andstem may be made of glass, wood, hard rubber, metal, or any otherdesired material.

Over the mouth of the bottle and abovel the tube B is secured a cap E,of metalor any desired material. This cap is provided with a centralprojection E', extending down to the upper end b of the tube B. Thisprojection is formed with a central hole through it, the lower portion eof which is somewhat larger than the upper portion e. In the cap E atone side of the center is formed an outlet-opening a, having a shortnipple, to which, if desired, a curved dispensing-spout may be attached,as shown. The lower portion of the projection E from the cap is formedwith an opening e2 in its side. The cap E is tightly fitted over themouth of the bottle and has an overlapping flange f, that extends downthe Outside of the bottle-neckand is crimped or compressed around theexternal rib a to hold the cap against being forced olf. When the cap Eis thus seated over the mouth of the bottle, its central hole e receivesthe upper end of the valve-stem d, the valve being held to its seat bythe pressure of an air-cushion in the bottle.

To dispense the contents of the bottle, it is only necessary to pressdown the valve D, and then the liquid passes up through the end b of thetube and out through the opening e2 in the side of the projection E andthence out through nipple a. For this purpose a detachabledispensing-key F is provided, whose stem is of a size to pass throughthe smaller e in the projection E and whose top part is fashioned into abutton. This key may have either a plain stem or it may bescrew-threaded. By pressing upon this button after the stem is insertedin the hole e the valve-stem d is forced4 down with valve D against theinternal pressure of the bottle. The valve D is made small enough to beforced through the lower open end of the tube when inserting the same,and when it reaches the enlarged chamber b it moves freely andsensitively to the depression of the key.

In filling the bottle it is intended to do so under an air-pressure ofsixty pounds, more or less, and a suitable filling apparatus is designedto enter the neck of the bottle and IOO seize and hold the valve-stemci, so that the valve will not be allowed to pass beyond the enlargedchamber. As there is a permanent cushion of air above the liquid in thebottle, it will be seen that this air-cushion Jforces the liquidcontents of the bottle up the tubevB whenever the valve D is depressed.If there is any attempt to reiill the bottle, the valve D will enter thetube B below, and its stem will leave the opening e, and the valvecannot again close upwardly on its seat. lf the valve passes down to thebottom of the tube, it will then strike against the bottom of the bottleand will be expanded to a tight lit that will prevent the passage of anyliquid into the surrounding space in the bottle.

The stem of the dispensing-button F is made relatively short, so thatthe button will strike the top of the cap before the valvestem is out ofits hole e, thus preventing the valve-stem from getting out oil place,which would prevent the proper closing ofthe valve on its seat.

A manufacturers seal S is secured around the top of the bottle-cap,which seal must be broken in any attempt to remove the cap and reiillthe bottle. This seal` as shown, is constructed as a ring which embracesthe cap from above the rib a to a point below flange 3o f and which isbroken in any attempt to release the iiangef of the cap from the rib.

I claim- 1. A bottle having in its neck a central pendent tube openinginto the bottom of the bottle and having at its upper end an enlargedportion terminating in a valve-seat, a valve located in this enlargedportion and having a stem extending above the same and a cap with a holethrough it in line with the valve-stem. f

2. Abottle having a contracted neck'portion and a central tube with anenlarged valve-chamber suspended upon the contracted portion of thebottle-neck and cemented therein, a downwardly-opening valve in thevalve-chamber and means for opening the same.

3. A bottle having a central tube suspended in the neck and opening intothe bottom of the bottle, said tube being made with an enlargedvalve-chamber and having a depressible valve therein and a cap arrangedover the mouth of the bottle and having a central projection with anopening through lit and also a lateral opening at its lower end.

4. A bottle having in its neck a suspended tube opening into the bottomof the bottle, enlarged at its upper end to form a valvechamber andhaving above the valve-chainber an opening smaller than the diameter ofthe tube and a valve arranged in the valvechamber and made smaller thanthe lower portion of the tube and larger than the outlet at the top ofthe tube.

5. A bottle having in its neck a suspended tube opening into the bottomof the bottle and an enlarged valve-chamber atits upper end with acontracted upper end, a valve in the valve-chamber and a cap for thebottle with a central stem extending to the top of the tube and having acentral hole for giving access to the valve.

6. A bottle having in its neck a suspended tube opening into the bottomof the bottle and an enlarged valve-chamber in its upper end, a valve inthe valve-chamber having an upwardly-projecting stem and a cap having adownward projection formed with a central opening of two diameters, thelower one being of larger diameter and receiving the valvestem.
